CHARLES H. HELMS, OF POUGI-IKEEPSIE, NEl/V YORK.

BURNlSHlNG-MACHINE FOR BOOTS OR SHOES.

TJPECIFICATIQN forming part of Letters Patent No. 302,335, dated July 22, 1884-.

Application filed November 30, 1883.

To all whom, it may concern: Be it known that I, CHARLES H. HELMS, citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented new and useful Improvements in Boot and Shoe Sole Edge Burnishing Machines, of which the following plan or top view, partly in section.

Similar letters i ndicate corresponding parts.

The letter A designates the machine-frame, supporting a driving-shaft, I3, which is providedwith a pulley, B, for connectingitwith a suitable power medium.

G indicates a crank-shaft arranged substantially in the horizontal plane of the drivingshaft, and E a flexible shaft connecting one end of this crank-shaft to the driving-shaft, so that a revolving motion imparted to the driving-shaft is transmitted to the crank-shaft. At the end opposite to the flexible shaft Ethe crank-shaft (l is provided with an eccentric pin, G, which constitutes its crank, and which engages a tool-stock, F, for imparting to the:

latter an oscillating motion, this stock' being mounted on a pivot, F, and being bifurcated at one end to receive the crank. Both the crank-shaft O and the tool stock F are supported ina carriage, G, which is capable of a reciprocating motion lengthwise to the shaft, it resting in a guide, J, which is adapted to permit the carriage also to swivel, this guide being composed of an eye the diameter of which is substantially equal in one direction, but greater in the opposite direction, to that portion of the carriage passing through it. The swivel-eye J is supported on aspring, K, and is connected with a treadle, N, through the medium of a rod, 0, for depressing the eye, together with the carriage G and its concomitants, against the action of the spring.

(No model.)

In applying the machine to use the boot or shoe is properly mounted in the jack 1?, and a burnishing-tool, Q,'is united to the tool-stock. A revolving motion is then imparted to the drivingshaft B, and in the ensuing motion of the tool, together with its stock, the burnishing of the sole-edge may be speedily accom-' plished, dueto the variety of positions which the tool is capable of taking-that is to say. by the reciprocating motion of the carriage G the tool can be readily adjusted to the location of the sole-edge while, by the swivel-eye J or treadle N, (either or both,) the tool can be readily adjusted to the depth of such edge, the crank-shaft O at the same time remaining in gear with the driving-shaft, so that the motion of the tool continues in any of its positions.

The burnishing-tool Q, shown in the drawings is provided with two faces, Q Q one of which is single and serves to act on the forward portion of the sole, while the other is double and serves to acton the shank portion, at which point the sole has two edges to be burnished, and it is evident that by this construction the utility of the tool is materially increased.

In order to decrease the area of motion of the burnishing-tool, the jack 1? is rendered movable in a circular plane by means of a rotating spindle, R, by which the jack is supported in a fixed bearing, S, the latter being constructed with a concentric guide, S, for the jack to steady it in its adjustment to the tool.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the driving-shaft,the reciprocating carriage carrying the pivoted oscillating tool-stock, the crank-shaft revolving in and reciprocating with the carriage, and having its crank engaging one end of the toolstock, and a flexible shaft connecting the driving and the crank shafts, substantially as described.

2. The combination, substantially as hereinbefore described, of the drivingshaft, the crank-shaft, the flexible shaft connecting the crankshaft to the driving-shaft, the oscillating tool-stock engaging with the crank of the crank-shaft, the reciprocating carriage supporting the crank-shaft and tool-stock, and l forming 2L guide for the carriage, the spring the guide for the carriage, adapted to permit supporting the eye, and the treadle connectthe latter to swivel. ing with the eye.

3. The combination, substantially as herein- In testimony whereof I have hereunto set 5 before set forth,of the driving-shaft, the ClZbIlkmy hand and seal in the presence of two sub 15 shait, theiiexible shaft connecting the crankscribing witnesses. shaft to the driving-shaft, the oscillating tool- CHARLES H.
